Old schema.sql created tables with inline UNIQUE column constraints,
which PostgreSQL auto-names as <table>_<column>_key. GORM expects
uni_<table>_<column> (its NamingStrategy convention). On upgrade,
AutoMigrate issued DROP CONSTRAINT uni_... against a name that did not
exist, crashing startup with SQLSTATE 42704.
Add preparePostgresLegacySchema() that runs before autoMigrateAll and
renames all five mismatched constraints:
- vite_config_name_key -> uni_vite_config_name
- peer_share_token_key -> uni_peer_share_token
- peer_share_runtime_reservation_id_key -> uni_peer_share_runtime_reservation_id
- peer_share_runtime_resource_key_key -> uni_peer_share_runtime_resource_key
- federation_tunnel_binding_resource_key_key -> uni_federation_tunnel_binding_resource_key
The function is idempotent: it checks information_schema before each
rename so re-runs on already-migrated databases are no-ops.
